Notes:
5. Dropout voltage is the voltage difference between the input and the output at which the output voltage drops 2% below its nominal value.
This parameter only applies to output voltages above 1.8V.
6. Test conditions for SOT23 and SOT23R: Device mounted on FR-4 substrate PCB, with minimum recommended pad layout, 2oz copper, single
sided.
